On an older battery like that, the sulfation from a complete discharge probably killed it. These aren't meant to go that low, ever. Deep cycle batteries are constructed differently.
Factory battery was 500 CCAs in many XJs. Find something close to that size with the best warranty possible. No need for this 90000 CCA marketing junk that will just short out on a gravel road because the plates are too tightly packed.
Update put charger on 10amps for about 4hours starts and idles fine now.Will buy a new battery today anyway.Had no idea a low battery could cause no idle,I thought as long as it was strong enough to start it would be good.Thank every one for you input.

That is because the alternator is not design to charge a dead battery.
The #1 cause of engine stalling on the 4.0 is a marginal battery. And before you ask, yes....you can have a battery that is strong enough to start the engine, but marginal enough to give the engine management system fits and stall the engine. It happens all the time. If this was a simple battery connection issue, tightening those connections may have resolved your problem, your alternator recharged your battery (you were symptomatic while this was happening....that is why you had to stay on the throttle) and the symptom disappeared as soon as the battery was adequately charged. But if it ever returns, get your battery "load tested". Load testing is the only accurate way of determining battery condition. Any parts store will do this for you for free. Keep us updated!
that's why I like my 96 4.0 because it's distributor ignition, I don't like coil on plug...
Year: 1998 Classic (I'll get it running soon....) and 02 Grand

Yep. A little overkill is not a bad thing thing, like maybe in the 600s.
Don't listen to the people advising something in the 800 - 900 CCA range for these vehicles. Sorry, but that's just a stupid waste of money, like installing # 0000 welding cables for battery cables. It doesn't do anything good for you, functionally.
All they are doing is buying bragging rights. "Look at ME! I've got the biggest! Yay! I'm a MAN!"
Unless you are going to be spending time using a winch with the vehicle off, you don't need or want a deep cycle battery.
If you ARE doing that, the right solution is a second battery with an isolator of some kind.
Just got a new battery today and mine still cuts off!
